What do we need from stakeholders?
We are seeking your input to this review. Submissions to this Issues Paper are due on Friday 31 October 2025.
On 14 October 2025 we will hold our first public workshop for this review. This public workshop will allow stakeholders to ask questions, raise issues and comment on the matters raised in the issues paper. We will consider all stakeholder feedback, as well as input from any external consultants and our own analysis, before publishing a Draft Report with our draft decisions in December 2025.
Stakeholders who would like to be notified when relevant material is released can subscribe to receive updates from IPART.
Why are we reviewing the discount rate methodology?
We are reviewing the methodology to ensure that our local government discount rate is suitable for councils using an NPV approach for contributions plans. Using an NPV approach should help councils recover sufficient revenue from local infrastructure contributions to recover costs of serving the remaining development in present value terms.
Why is the discount rate important?
For contributions set using an NPV approach, the discount rate for local government contributions plans influences the contributions that developers must pay to councils to fund the local infrastructure that their developments require.
